Best sticky skin or lingerie tape I have come across. It sticks! But once put down, don't reposition it. It comes in a roll so you can cut off whatever length you want.
The tape is difficult to separate from it backing at first. Once you have done it, make sure after cutting off a piece you require, you leave a bit of the backing longer than the sticky tape, so the next time you get to use it you don't have the problem of trying to separate the two!
I bought two tapes even though I still have the first roll, only because I don't want to be disappointed if later I try to get it and it is out of stock. I'd recommend buy two rolls. You won't be disappointed. I use it with very revealing necklines to keep the shoulder in place so the dress doesn't fall lower than I like, or cross-over fronts to pin the two crossover panels in place so they don't open out if I move about. I use it to keep straps in place, to hide peeping lace from my slip underneath, or bra.
